Retired LPD Capt. Dwayne Prejean arrested again

Four days after he was charged with battery, retired Lafayette Police Capt. Dwayne Prejean was arrested Saturday on a drunk driving charge, jail records show.

Prejean was arrested around 1 a..m. Saturday on charges of operating while under the influence and driving on right side of the road, booking reports from the Lafayette Parish Correctional Center indicate.

On Jan. 23, Prejean was arrested on one count of domestic abuse battery. His wife, Lafayette attorney Allyson Prejean, was booked at the same time on one count of aggravated battery with a dangerous weapon.

Their charges stemmed from an alleged argument between the two that began at a restaurant/bar New Year's Eve.

Dwayne Prejean, who at one time was head of the Lafayette Police Department's narcotics unit, was placed on paid administrative leave the prior week when the department launched a criminal and internal investigation.

Before his arrest Jan. 23, a department spokesman said Dwayne Prejean retired, but the criminal investigation would continue.

"Neither the criminal nor the IA (internal affairs) investigations are finalized," Joy Rabalais, an attorney who reviews public records requests for the police department, told The Daily Advertiser Wednesday in response to a public records request.
